Singing out of tune: sexual and developmental differences in the occurrence of nonlinear phenomena in primate songs Open
Animal vocalizations contain a varying degree of nonlinear phenomena (NLP) caused by irregular or chaotic vocal organ dynamics. Several hypotheses have been proposed to explain NLP presence, from unintentional by-products of poor vocal tec…

Quantifying Facial Gestures Using Deep Learning in a New World Monkey Open
Facial gestures are a crucial component of primate multimodal communication. However, current methodologies for extracting facial data from video recordings are labor‐intensive and prone to human subjectivity. Although automatic tools for …

Discrimination between the facial gestures of vocalising and non-vocalising lemurs and small apes using deep learning Open
Facial expression studies in animal communication are essential. However, manual inspection methods are only practical for small datasets. Deep learning techniques can help discriminate facial configurations associated with vocalisations o…

Isochrony as ancestral condition to call and song in a primate Open
Animal songs differ from calls in function and structure, and have comparative and translational value, showing similarities to human music. Rhythm in music is often distributed in quantized classes of intervals known as rhythmic categorie…

Who you live with and what you duet for: a review of the function of primate duets in relation to their social organization Open
Duets are one of the most fascinating displays in animal vocal communication, where two animals fine-tune the timing of their emissions to create a coordinated signal. Duetting behavior is widespread in the animal kingdom and is present in…

Vocal tract shape variation contributes to individual vocal identity in African penguins Open
Variation in formant frequencies has been shown to affect social interactions and sexual competition in a range of avian species. Yet, the anatomical bases of this variation are poorly understood. Here, we investigated the morphological co…

Isochronous singing in 3 crested gibbon species (<i>Nomascus</i> spp.) Open
The search for common characteristics between the musical abilities of humans and other animal species is still taking its first steps. One of the most promising aspects from a comparative point of view is the analysis of rhythmic componen…

Singing more, singing harsher: occurrence of nonlinear phenomena in a primate' song Open
Nonlinear phenomena (NLP) in animal vocalizations arise from irregularities in the oscillation of the vocal folds. Various hypotheses have been put forward to explain the occurrence of NLP, from adaptive to physiological ones. Non-human pr…

Parent-offspring turn-taking dynamics influence parents’ song structure and elaboration in a singing primate Open
Parent-offspring interactions are essential to interpret animal social evolution and behavior, but their role in mediating acoustic communication in animals that interact vocally is still unclear. Increasing evidence shows that primate voc…
